How can i write a slope intercept form of an equation with a line through the given points?

Pick two random points on the line. now use the equation y=mx+b.

B is the y-coordinate of the y intercept. for example, if the y-intercept is at 0, 1, you would only write 1 in place of B.

M is the slope of the line, written in fractional form. I'd assume you know how this works.

X means nothing other than X, I think.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
